(GRANTED UNDER THE rRovIsIoNs oETHE `ACT E MARGH 3, 1921, 41 STAT. L., 1313.)

To' all whom 'it may cpvwcrn Be ltpknown that we, F nANoIsoo RIVIERE and FERNANDO,` RIvIEnE, both subjects of the fcation." .i t This Invent-ion` is an improvement 1n the` 4King of spaimresiding at Ronda de San `Pedro1, Barcelona, in Spain, have invented certain Improvements in Apparatus for the Manufacture of WirefNettinfr, (for which we have led applications in Sopain, March 3,

I 1917, No. 64,053; France, March`2, 1918, No.

20,729; Great BritainpMarc-lrl, 1918, No. 113,968, and in Germany March 4,1918, No. 73,843,) of `which th following is a specifiapparatus describedand claimed by us in ourco`-pending application for Letters Patent SerialNo 103861, filed 15th June, 1916, an the said improvement consists in adapt- 1 1 ingthe apparatus to the manufacture of` net-` ting of the type wherein reinforcing wires are introduced into, the fabric, in a manner which will be made clear in the following description of the invention.

Theinvention is illustrated in the accompanying drawings, in whch F lgure 1 representsa samplewof `netting made with the improved apparatus, and

portion of the receiving Fig. 2 showsla t drum of the machine, with finished fabric thereon. t t 1. 1 ,o

Fig. 3 is a vertical section of part ofthe i apparatus,l including the receiving drum,

4.o` t 1 meshes of the fabric` are formed by wires 24 Fig. 411s a plan View" weer, `with ai@ drum removed.

` 1 Figs. 5 and 6 are side views, fronidiferent angles, of vone of thenet engaging pins on the; receiving drum, drawn to a scale than Figs. Sand 4. o, o 1

Asbest shown in Fig. ,1,y theyhexagonal rger " and 25,` twisted together at the junctions or 1 sides of the meshes, the twist being 1n opposite directionsabove and below the compara tively straight parts26 ofthe wire. In addition to the wires 24 and 25 there are fre-` inforcing wires 27, extending through the abricand vertically intersecting each mesh intheir course, these wires 27 beingtwsted to ether with the wires 24 and 25 as shown.

he apparatus described in our prior speci- 11 cation 1 cited produces fabric composed solely ofwires such as the wires 24 and 25,

which may be designated mesh forming ever, combined with means for introducing the reinforcing wires 27.

The mesh forming wires pass through guides 1 and 2 (Figs. 3 and 4) rec-iprocable t in a channel in a. bed 3. Upon the said bed is a carrier 4:,` carrying a series of rotatable `twisting wheels, three of which are shown inFig. 4, designated 20, 21 and 22. These wheels have teeth 33 engaged with a rack 5 Islidable in the carrier, and each wheel has an axial bore118, flared in opposite directions from a narrow central part or throat, a radial slot giving access to this bore from one side of the wheel, as best shown in F :ig-4. The mesh forming wires, of which Fig. 4 shows `three pairs designated 10-11, `12h13, 11i-15 pass through holes 6 and 7 in the guides 1 and 2 respectively.

All these elementsof the apparatus are found in our yprior specification, and the manner of their operation, to be described hereinafter, is the same as in that specification. The intermittently rotating receiving drum 34, however, differs from that shown in our prior specification, in that. the pins thereon `for engaging the netting are split, i `each pin having two aws 37, 3811(Fig. 5)

diverging to form a -shaped gap adapted to receive one of the reinforcing wires when o the 1:pin engages the top of a mesh, as shown `1n ment of the latter does not affect them.`

With `the parts in the position` shown in Figs. 3 andheach twisting wheel has passing through its bore one pair of mesh forming, wires and one reinforcing wire, the reinforcing wire lying between the mesh forming yifires."` The first step`from this position, is" the movement of the rack 5, say, in the direction of the arrow C; by this means the twisting wheels are rotated, and each wheel twists together the wires which it engages, producing a twist such as shown in Fig. 1. The drum 34 then rotates, as

indicated by the arrow F, and the carriere, with the twisting wheels7 recedes from the wires, as indicated by the arrow D, where upon the wire guides l and 2 are moved in opposite directions, las indicated by the ar-V rows A and B, to bend apart the mesh forming wires and re-group them with the reinforcing wires, which remain stationary. The carrier 4c, which has meanwhile been traversed laterally in the direction of the arrow E, through a distance equal to half the width of a mesh, then advances toward the wires, so that the twisting wheels rengage the wires, whereupon the rack 5 is again actuated, and the wires receive another twist, and so on.

In the, following cycle of operations the parts l, 2, and a move, of course, in the directions oppositeto those indicated by the respective arrows.

Instead of moving both the wire guides,

vone of them may remain stationary, the

travel of the other being doubled, producing a trapezoidal mesh.

It will be understoodthat it is not essential to have a reinforcing wire for each longitudinal series of lmeshes- VThese wires may, for example, be restricted to alternate series of meshes, or used inany other selected order. rIhesaid wires may also be yof dierent thickness to the mesh forming wires, and may becomposite, in the form ofA p cables or thev like. v

a plurality of twisting wheels having axial y v for guiding through the machine a series of r bores and slots giving lateral access to said bores, for engaging'thewires, a carrier for said wheels, reciprocable Vinto and from'cooperative position with said mesh forming wires and said'reinforcing wires, and also reciprocable laterallyA of said rows of wires, and means for rotating said wheels in both the positions to whichthey are movable by the lateral reciprocation of said carrier.

2. In a wire net machine two parallel wire v`guides, each arranged to guide a row of spaced apart mesh forming wires, means reinforcing wires parallel with the mesh forming wires prior to the formation of the mesh, a plurality of twisting wheels having axial bores and slots giving lateral access to said'bores, for engaging the wires, a carrier1 for said wheels, reciprocable into and from cooperative position with said mesh forming wires and said reinforcing wires, and also reciprocable laterally of said rows of wires, and means for rotatin said wheel in both the positions to which they are movable by the lateral reciprocation of said carrier, said wheel rotating means including teeth on said wheels and a rack engaged with said teeth.

3. In a wire net machine two parallel wire guides, each arranged to guide a row of spaced apart mesh forming wires, a net receiving drum above said guides, net engaging members upon said drum, each of said members having two divergent jaws adapted to engage and guide a reinforcing wire extending upward from between said parallel wire guides, a plurality of twisting wheels having axial bores and slots giving lateral access to said bores for engaging the wires, a carrier for said wheels, reciprocable into and from cooperative position with said mesh forming wires and said reinforcing wires, and also reciprocable laterally of said rows of wires, and means for rotating said wheels in both the positions to which they are movable by the lateral reciprocation of said carrier.

4. In a wire net machine two parallel wire guides, each arranged to guide a row of spaced apart mesh forming wires, said guides being oppositely reciprocable one half the width of a mesh, an intermittently rotating net receiving drum above said guides, split net engaging pins upon said drum, each having a V-shaped mouth adapted to vengage and guide a reinforcing wire ascending to said drum from between said parallel guides, a plurality of twisting wheels, each having an axial bore and a slot giving lateral access to said bore, a carrier for said wheels reciprocable to move said wheels into and out of engagement with said mesh form ing wires and said reinforcing wires, and also reciprocable laterally of said rows of wires one half the width of a mesh, and means including a rack and teeth on said wheels, for rotating the latter in both the positions to which they are moved by the lateral reciprocation of said carrier.

In witness whereof we have signed this specification in the presence of two witnesses.
